HRM-45 Rockwell Hardness Tester
Introduction
Rockwell hardness test is a simple instrument to test the hardness value of hard metals, carburized steels, quenched steels, hard cast irons, mild steels, Al-alloys, Cu-alloys and malleable irons according to Rockwell Principle according to ISO 6508 and ASTM E18. It measures the depth difference between the primary and testing load and convert the depth difference to the hardness value. These machines can be operated semi-automatically. They are essential testing instruments for quality testing section, university and college, research institution and industrial laboratory.
Features
Model HRM-45 is superficial Rockwell test scales N & T (15/30/45kgf) with dial indicator and hand control loading.
Model HRM-45DT is superficial Rockwell test scales N & T (15/30/45kgf) with dial indicator and motor control loading.
